    Abstract: A system for distracting two tissue surfaces away from one another within a spine, involving a plurality of biocompatible and generally rectangular spinal inserts configured to be successively stacked within a spine to distract the two tissues surfaces away from one another. Each spinal insert has a generally planar top surface having a leading edge and a trailing edge, a generally planar bottom surface disposed generally parallel to the top surface and including a leading edge and a trailing edge, and a beveled surface extending from at least one of the leading edge of the planar top surface and the leading edge of the planar bottom surface. The beveled surface is configured to allow a currently inserted spinal insert to be positioned at least one of above and below a previously introduced spinal insert to distract the two tissue surfaces.

    Abstract translation: 一种用于在脊柱内分散彼此远离的两个组织表面的系统，其涉及多个生物相容性和大致矩形的脊柱插入物，其构造成连续地堆叠在脊柱内，以将两个组织表面远离彼此分散。 每个脊椎插入物具有大致平坦的顶表面，其具有前缘和后缘，大致平坦的底表面大致平行于顶表面设置，并且包括前缘和后缘，以及从至少一个 平面顶表面的前缘和平面底表面的前缘。 倾斜表面被配置为允许当前插入的脊柱插入件被定位在先前引入的脊柱插入件的上方和下方中的至少一个以分散两个组织表面。

    Abstract: An implant is provided for performing spinal fusion. The implant includes an implant body having a leading side and a trailing side at opposing ends along a longitudinal axis. Between the leading side and trailing side are an upper surface, a lower surface, an anterior side, and a posterior side. At least one keel structure is provided extending from the implant body for penetration into an adjacent vertebral body. A trial sizer and keel cutter may be utilized to form keel channels within the vertebral body to receive the keel structure.
